Immediately upon numerals, 1 indicates a casing of any desired the leaves passing this finger they swing down- 50 kind provided with a large window opening 2 as wardly to the lower position as shown in Fig. 4

i illustrated in Fig. 4. Within the casingl is arso that the front face of the upper card and ranged the various moving parts of the device the rear face of the lower card will be seen, as and in addition a frame 3 which has a base plate shown in Fig. 1, but when the card swings to its 4, uprights 5 and 6, and a top plate I. The uplower position it strikes a spring-held stop or catch 29. This stop may be formed of metal or other material and suitably mounted on a pin which also holds a spring 3| in place. One end of the spring 3| may be embedded in a block 32 and the other end in the catch 29 so as to resiliently hold the catch in the position shown in Fig. 1. When the leaves 2l swing downwardly there is sufiicient power topermit the same to snap past the catch 29, but if the lower leaf attempts to swing back the spring 3| is sufficiently strong to prevent any backward swinging movement and thus the upper and lower leaves are held as shown in Fig. 1 until the upper leafis released by a proper turning movement of the shaft l0 and the hub structure.

The shaft I 6 may be rotated "by' power or by hand. This shaft has a hand wheel 33 rigidly secured thereto, which may be actuated at .any time to turn the hub structure slowlyor quickly. This is of advantage when it is desired'to replace one or more;cards .23. -When this is the case, the hand wheel is rotated rather 'rapidly until the card to 'be removed appears as the upper card. This card is removed, a new one substituted, and :the hand wheel '33 further rotated if the second card is to be removed. This action may take place either while the power structure hereinafter fully describedis-stationary or functioning.

The power structure is designed'to'rather slowly move the hub structure and the workmen'need not wait until the described card appears but may quickly bring the desired card to view by a manual actuation of the wheel 33. The shaft 16 is also squared at 34 sothat a :key may be inserted into the housing and the shaft properly actuated. Thepower structure includes a prime mover 35 which may be an :electric motor. The electric motor rotates a sprocket wheel .36 which causes a chain 31 to .function,.and .this chain 3 is fitted over a large sprocket wheel .38. The sprocket wheel-38 is rotatably mountedon a .supportingjshaft -39 carried by the upright'6, while a small sprocket All is rigidly secured .to sprocket Wheel 38 and is therefore rotated thereby. .The chain 4| is fitted on the sprocket 40 and also on alarge sprocket wheel-42, which large sprocket wheel is looselymounted on shaft 1.0. A ratchet wheel 43 is rigidly secured .to shaft .10 by set screw 44 or other suitable means. The-sprocket wheel 42 carries a spring-pressed pawl 45 so that whensprocket wheel 42 is rotatedin one direction the shaft Ill will be likewise rotated. A second ratchet wheel 46 is alsorigidly secured to shaft 10 by aset screw or other. suitable means, and a spring-pressed pawl 41 coacts with the ratchet wheel 46 so as to prevent any reverse rotation of shaft 10. When the hand wheel 33 is rotated the ratchet wheels 43 and 46 willalso berotated but sprocket wheel 42 will not be rotated. By reason of this construction the ;hand wheel 33 may be used either while the motor 35 is stationary or while it is functioning.

As shown particularly in Fig. 1, the various pins 24 and 25 are approximately twice the length of the hub members I .l and though they could be slightly more than-twice the length. This is to allow the leaves 2| to-beremoved and applied whenever desired. When the 'parts arearranged as shown in Fig. 1 the leaves are locked in position, but if it should be desired to remove one of the leaves the retaining plate '48 is moved to the left as shown in :Fig. 3. This will permit an -.operator to;grasp;one=.of the leaves, as for :instance the lowermost leafnand slide the same 56 is "hingedly connected at 5'! andis provided with aslot 58 for has been inserted the plate 48 is returned to the position shown in Figs. 1 and 2. This looks or holds the leaves against accidental removal.

.The'plate 48 is provided with a hub 49 as shown in Fig. 3. This hub is provided with an annular groove 50 intowhich the respective pins 5| extend. These pinsare carried by a suitable yoke 52 that is connected to a lever 53. The lever l5.3; is ..pivotally.mounted at 54 on a bracket 55 secured to the upright 6. A sliding locking plate to the lower end 56 is manually actuated accommodating a retaining pin 59. A second slot *66 accommodates a pin 6|, which pin has a head adapted to fit into a socket or depression 62 (Fig. 3). A

.of lever 53. The plate spring .63 acts to swing the outer end of plate 56 upwardly as shown in Fig. 1, so that the head of the screw 6| will automatically snap into the depression '62.

'When'in the position'shown in Fig. '1, plate 48 is locked against movement but'if it should be desired to slide the same to the position shown in Fig. 3 the outer end of plate 56, as shown in Fig. -1,is depressed and pulledto-the right. This will swing the lever 53 until the plate .48 is in the position shown in Fig. 3. This will allow leaves to be removed and added.

In order to prevent a workman from .inadvertently leaving the parts in-the position shown .in Fig. .3 after changing a leaf, a special switch arrangement has been provided as shown particularly in Fig. 1. When the .member 56 is pulled to the dotted position as shown in Fig. 1, lever 53 will be swung to the left at the upper end so as to .bring the plate .48 to .the position shown in Fig. 3.

.This willpush the rod .64 so .that it will open the switch 65. It will be observed that switch 65 is inserted inthe wiring 66 of motor35. The hand switch 6'! is also inserted in the same wiring so that the motor may be turned on and off manual- .ly whenever .desir-ed. However, when. the parts are in the position shown in Fig. 1 the device is operated, but if a workman should open switch 6'! to stop the machine and thenpull motor56 outwardly tothedotted-position shown in Fig. 1 in orderto move plate 48 away from the hub member H,-switch-65 would also be opened. After the leaves have been addedor removed the workman can close switch 61 but the device will not start until ;plate .56 has been slid back to its normal position, whereupon switch 65 will be closed and plate 48 will be moved against the hub member I I. Normally when the machine is operating and it is desired to remove a leaf, plate 56 is moved outwardly without touching the hand switch 61. This will :stop the machine butthe workman may operate the hand wheel 33 for rotating the parts in order to remove the desired leaves. After the leaves have been removed or added, the machine cannot be started until plate .56 is pushed back to the full line position shown-in Fig. 1.

In Figs. 7 to i10 inclusive asllghtly modified form of construction isshown wherein the sliding plate 48 is eliminated and the various parts asso-- ciated therewith. :In this form of the invention instead of moving the plate when removing a leaf, a spring is bowed as shown in Fig. 10. It will therefore be seen that a plate 48' is held against the hub member II but does not rotate therewith. This plate is provided with a tubular extension 68 which is formed with an annular flange 69 secured by suitable means, as for instance screws Ill, to the upright 6. The plate 48 is cut away near the periphery for forming a notch 1| and the enlarged offset end 12 of spring 13 fits into this notch as shown in Fig. 9. Suitable rivets or other securing means 14 rigidly secure one end of the spring 13 to the plate 48'. This plate is positioned so that the notch 1| will be facing any one looking at the sign. It will therefore be seen that the two leaves facing an observer, as shown in Fig. 1, will have their pivotal members opposite the notch II. By moving the upper leaf to the left, as shown in Fig. 10, spring '53 will be bowed and the leaf disengaged from the hub member l2. A reverse movement will remove the pivotal point from the hub I I so that a new leaf may be substituted if desired. The spring 13 is sufiiciently strong to prevent this movement unless performed by a workman.
